button is pressed, the voltage at
which the test results were taken
is recalled to the display. After a
short time, the display will again
indicate the applied voltage (if
any) in real-time.

4.2 Operating Procedures
Normal Test
1.
If you are using the KATC-V without one of the Knopp Transformer
Testing Systems, connect the standard transformer and transformer-
under-test as shown in Figure 1 (earlier in this manual). When using
the KATC-V with the KVTS or 1G2, refer to the instruction manual for
your system for transformer connection instructions.
2.
When power is first applied to the KATC-V, the display will momen-
tarily show
RESET
. After this message disappears, test voltage data
is displayed.
3.
Slowly
adjust the test voltage (secondary voltage of the Transformer)
to the desired value.
Note that the data will not be displayed until
the Test Voltage reaches 10 VAC!!!
U
CAUTION
IF THE TEST VOLTAGE IS APPLIED TOO QUICKLY, THE
KATC-V ALARM MAY BE FALSELY TRIGGERED. ALTHOUGH
THE KATC-V HAS CIRCUITRY TO MINIMIZE THE EFFECTS OF
EXCESSIVE ERROR VOLTAGE, THE PROTECTION IS NOT
TOTAL. IF A GENUINE ERROR CONDITION EXISTS (WRONG
POLARITY OR WRONG RATIO), APPLYING VOLTAGE TOO
QUICKLY WILL INCREASE THE CHANCES OF DAMAGE TO THE
KATC-V AND TO ASSOCIATED EQUIPMENT.
4.
After the data is displayed (RATIO ERROR, PHASE ERROR, and
ACCURACY CLASS), press HOLD/PRINT
— then reduce the volt-
age to zero.
The HOLD status is denoted by the appearance of a “box” (

) on
